BLE HAS OCCURRED

Question

Answer (not a malfunction)

Mechanical sound is heard from the indoor unit.

The air flow direction changes during operation.

Water leaks from the outdoor unit.

Air does not blow out soon in the heating operation.

The operation is stopped for about 10 minutes in the heating operation.

Hissing sound is sometimes heard.

The air conditioner starts the operation only with the main power turned on, though you do not op- erate the unit with the remote controller.

■This is the switching sound in turning on/off the fan or the compressor.

■When the air conditioner is operated in COOL or DRY mode, if the operation continues with air blowing down for 1 hour, the direction of the air flow is automatically set to horizontal to prevent condensed water from dropping.

■In the heating operation, if the air flow temperature is too low or when defrosting is being done, the horizon- tal vane position is automatically set to horizontal.

■During COOL and DRY operations, pipe or pipe con- necting sections are cooled and this causes water to condense.

■In the heating operation, the defrosting operation makes water frozen on the outdoor unit melt and drip down.

■In the heating operation, water condensed on the heat exchanger drips down.

■Please wait as the air conditioner is preparing to blow out warm air.

■Defrosting of the outdoor unit is being done (Defrost- ing operation).

Since this is completed in 10 minutes, please wait. (When the external temperature is too low and humid- ity is too high, frost is formed.)

■This is the sound when the flow of refrigerant inside the air conditioner is switched.

■These models are equipped with an auto restart func- tion. When the main power is turned off without stop- ping the air conditioner with the remote controller and is turned on again, the air conditioner will start opera- tion automatically in the same mode as the one set with the remote controller just before the shutoff of the main power.
